“…The PWM schemes for power converters can be broadly classified as high switching frequency PWM, such as sine PWM; space vector PWM; and low switching frequency, such as Selective Harmonics Elimination (SHE), Space Vector Modulation (SVM), and selective harmonics mitigations (SHM) schemes [1][2][3][4][5][6][7][8][9][10]. The high switching frequency PWM schemes (in kHz) are used in applications where power quality is of more importance than switching losses (mainly low power applications).…”

Considering the aim of having low switching losses, especially in medium-voltage and high-power converters, the pre-programmed pulse width modulation technique is very useful because the generated harmonic content can be known in advance and optimized. Among the different low switching frequency techniques, the Selective Harmonics Elimination (SHE) modulation method is most suitable because of its direct control over the harmonic spectrum. This paper proposes a method for obtaining multiple solutions for selectively eliminating specific harmonics in a wide range of modulation indices by using modified Newton-Raphson (NR) and pattern generation techniques. The different pattern generation and synthesis approach provide more degrees of freedom and a way to operate the converter in a wide range of modulation. The modified Newton-Raphson technique is not complex and ensures fast convergence on a solution. Moreover, multiple solutions are obtained by keeping a very small increase in the modulation index. In the previous methods, solutions were not obtainable at all modulation indices. In this paper, only exact solutions to the low-order harmonics elimination for Cascaded H-bridge inverter are reported for all modulation indices. Analytical and simulation results prove the robustness and correctness of the technique proposed in this paper.

“…Since most of the equipments used for domestic and industrial purposes are working on an AC source, the DC output from a PV system needs to be converted into an AC. For this, power inverters play a major role [1][2][3][4][5][6][7][8][9][10]. Two level inverters need high frequency carrier pulses in order to get better output performance.…”

Inverters are Power Electronic System (PES) and proficient to converting Direct Currents (DC) into Alternating Currents (AC). Conventional two-level inverter has drawbacks like high Total Harmonic Distortions (THD), high voltage across power switch, high dv/dt of output voltage and electromagnetic interferences. Multilevel Inverters (MLIs) are employed to overcome the drawbacks of conventional two-level inverter. Multilevel Inverters generate an AC voltage using small voltage steps obtained with the help of DC supplies or capacitor banks. This paper deals with the implementation of a Transistor Clamped H-Bridge Multilevel Inverter (TCHB-MLI) using Inverted Double Reference Single Carrier Pulse Width Modulation (IDRSCPWM) technique for photovoltaic application. The proposed TCHB-MLI requires less number of power switches and drivers to achieve maximum number of output level. The analysis of the multilevel inverter output is done in terms of its harmonic spectrum, output voltage and output current for modulation indices 0.85, 1 and 1.25. The control signals for the power switches of the proposed TCHB-MLI are developed by using SPARTAN 3E-XCS250E trainer kit. Experimental results will verify the functionality, design of the proposed TCHB-MLI and IDRSCPWM Technique.
